Crosslinking methods of waterborne polyurethane and commonly used crosslinking agents
What is crosslinking of waterborne polyurethane? The molecular chain of waterborne polyurethane resin is generally linear or branched, and the strength of the film without crosslinking is lower. In order to improve the water resistance, chemical resistance, high temperature resistance and mechanical properties of the cured film, it is necessary to appropriately increase the degree of […]
Service case | Use anti-hydrolysis agent to solve the problem of hydrolysis of TPU products
What is TPU TPU is short for thermoplastic polyurethane elastomer rubber. Compared with traditional plastics, rubbers, and even metals, TPU has many performance advantages such as good low-temperature flexibility, high strength, good oil and acid resistance, environmental protection, and easy processing. With economic development and consumption upgrades, the amount of TPU is increasing year by year. […]
What are the commonly used plastic additives?
The main purpose of adding additives to plastics is to improve processing performance, increase efficiency and reduce costs. Plastic additives occupies a small proportion in plastic materials, but they have a great impact on the quality of plastic products. Different types of plastics require different types and amounts of additives due to different molding processing methods […]
Service Case | Solve the hydrolysis problem of PET monofilament with HyMax hydrolysis stabilizer
【general introduction】 The drying filter used in the paper industry is made from PET monofilament. It is used in high temperature and humid environments for a long time. The PET filter is prone to hydrolysis reaction. Adding HyMax® hydrolysis stabilizer to the PET monofilament can extend the service life. It can reduce the frequency of shutting […]
Service Case | Extend the pot life of waterborne polyurethane by replacing the toxic isocyanate curing agent
The main material used by a customer in the post-processing stage of the product is two-component waterborne polyurethane, and isocyanate is used as the curing agent. However, during the specific production process, the customer found that if the formulated water-based polyurethane is not used up in time, the gel will deteriorate the next day and […]
Service case | replace the toxic curing agent in fabric printing industry with eco-friendly crosslinking agent
A clothing customer’s orders are mainly from the European Union. The EU has been strict in chemical control. Many batches of clothing exported by the customer were found containing chemical substances banned by the EU. The loss of direct goods and the sharp decline in subsequent orders have caused huge losses to the customer. After inspection […]
